1. A cable for data transmission, the cable comprising:
- a plurality of twisted pairs of insulated conductors including a first twisted pair and a second twisted pair, each twisted pair comprising two insulated conductors twisted together in a helical manner;
a binder substantially surrounding the plurality of twisted pairs of insulated conductors;
a jacket surrounding the plurality of twisted pairs of insulated conductors and the binder; and
a dielectric helixed spline disposed between the binder and the jacket along a length of the cable, the dielectric helixed spline providing an air gap between the jacket and the binder;
wherein the dielectric helixed spline comprises a fluoropolymer.

Abstract
Cables including a plurality of twisted pairs of insulated conductors and a jacket surrounding the plurality of twisted pairs of insulated conductors, the jacket including a plurality of protrusions extending away from an inner circumferential surface of the jacket toward a center of the cable. The plurality of protrusions are configured so as to hold the plurality of twisted pairs away from the inner circumferential surface of the jacket, and may provide an air gap between the plurality of twisted pairs of insulated conductors and the inner circumferential surface of the jacket.
